The very first versions of Zenit-15M were unsuccessful belorussian's attempt to issue an "Elite" type camera. Though cameras under name "Zenit-15M" are quite common to find nowadays, these conceptional versions had great sequence of shutter speeds 1s - 1/1000s + B and slightly different body design.

PB4605. Seems to be an earliest so far known prototype version of Zenit-15M camera. Very few pilot cameras released by BeLomo in 1988. Shutter speeds: 1/30s - 1/100s +B. Shutter advance knob with frame counter's disk. Shutter release knob in the center of the top plate. Fitted with Helios-44M-4 2/58 lens.

PB4610. Camera identical to PB4605, but under name "ALBAR" in Roman characters. Very few pilot cameras released by BeLomo in 1988.
